Abstract

4D neutron imaging is used to image flow and transport in porous rock and investigate the effect of carbonate precipitation The velocity field of injected fluid is estimated by solving the advection-dispersion equation using the contrast in neutron attenuation Carbonate precipitation widens the distribution of fluid velocities due to local pore-clogging

Keywords

calcium carbonate precipitation, fluid flow, neutron and X-ray microtomography, porous rock
